There are so many things to do that are not rides, it's ridiculous.
Animal Kingdom: Finding Nemo the musical, Festival of the Lion King, Flights of Wonder, It's Tough to be a Bug, Maharaja Jungle Trek (walk through) Pangani Forest Exploration Trail, midway games at Dino Land, you might get him onto the Kilimanjaro Safaris, because while it is a ride, it's just a truck that you ride through the habitats in.
Hollywood Studios: Fantasmic!, Lights, Motors, Action Extreme Stunt show, Beauty and the Beast Live, the American Idol Experience, Indiana Jones Epic Stunt Spectacular, Muppet Vision 3-D, Walt Disney: One Man's Dream (don't miss that), Disney Animation classes, Honey I Shrunk the Kids movie set, Jedi Training Academy, and again, you might get him on the Great Movie Ride, it's just a tram through movie sets that gets "hijacked" by mobsters or bandits and it's awesome.
Epcot: At the Seas the aquarium is amazing and I could have wandered around staring at the aquatic life for hours, Turtle Talk with Crush (even as an adult it's fun to watch), Circle of Life at the Land, along with the Livin' with the Land ride, which again is just a boat that floats through the sustainable foods areas, very cool and escapable, Illuminations, Innoventions, Captain EO, National treasures, the American Adventure and all of the other videos in each of the World Showcase pavilions, Chinese Acrobats (amazing), British Revolution (British cover band from the Beatles to the Kinks, really cool), Jammitors (band with a janitor gimmick that perform at certain times near the front of the park, really neat to watch), the Mariachi band at Mexico, Mo'Rockin at the Morocco pavilion (belly dancers!), and of course you can always take the Drink Around the World Challenge!
MK: Mickey's Philharmagic (don't miss, it's great), Country Bear Jamboree (a favorite from my childhood), Celebrate a Dream Come True parade, the Hall of Presidents, the Shooting Arcade, Monsters Inc Laugh Floor (don't miss, really fun if you get picked on), Swiss Family Treehouse walkthrough, the Tiki Room, Carousel of Progress, and the new Sorcerer's of the Magic Kingdom interactive game.
Not to mention Hoop Dee Doo Musical Revue dinner show, Spirit of Aloha dinner show, Pirates and Pals fireworks cruise, Mickey's Backyard BBQ and all of the just plain fun dining experiences like Prime Time 50s Cafe, Sci-Fi DIne In Theater, Biergarten, the Rainforest Cafe, T-Rex, etc.
